Retrograde revascularization of ostial left main CTO using internal mammary artery byepass graft: A case report

Percutaneous Coronary Intervention for Double Ostial Lesion Presenting with ST-Segment Elevation Myocardial Infarction: Chronic Total Occlusion at Left Main Ostium and Plaque Rupture at Right Coronary Artery Ostium

“…1 There are few reports regarding PCI for CTO at the LMCA ostium because bypass surgery is the best option for this high-risk lesion. [2][3][4] The patient in this case presented with a ST-segment elevation myocardial infarction, and received successful PCI for both critical lesions at the RCA ostium and CTO at LMCA ostium using an antegrade approach.…”

Prevalence and Outcomes of Percutaneous Coronary Interventions for Ostial Chronic Total Occlusions: Insights From a Multicenter Chronic Total Occlusion Registry

“…4,5 Some aorto-ostial CTOs, such as flush occlusions, may only be approachable using retrograde crossing (Fig. 1), and they often require creative selection of equipment, techniques [6][7][8][9][10][11][12][13] and imaging. [14][15][16][17] We examined a contemporary multicentre CTO PCI registry to determine the clinical and angiographic characteristics and procedural outcomes of ostial CTO PCI.…”
